It had been a directory authority since 0.2.1.20.

Fixes the 0.2.7 case of bug #19213, which prevented mingw64 from
working.

Had conflicts related to other correct_tm bugs in 0.2.6.  Added wday
for another case.

The tm_wday field had been left uninitialized, which was causing
some assertions to fail on Windows unit tests.

Fixes bug 18977.

In dirserv_compute_performance_thresholds, we allocate arrays based
on the length of 'routers', a list of routerinfo_t, but loop over
the nodelist. The 'routers' list may be shorter when relays were
filtered by routers_make_ed_keys_unique, leading to an out-of-bounds
write on directory authorities.

This bug was originally introduced in 26e89742, but it doesn't look
possible to trigger until routers_make_ed_keys_unique was introduced
in 13a31e72.

Fixes bug 19032; bugfix on tor 0.2.8.2-alpha.

This makes our compilation options checks in autoconf work better on
systems that already define _FORTIFY_SOURCE.

Fixes at least one case of bug 18841; bugfix on 0.2.3.17-beta. Patch
from "trudokal".

Fixes bug 19008. bugfix on 0.2.7.3-rc

Also, put libor-testing.a at a better position in the list of
libraries, to avoid linker errors.

This is a fix, or part of a fix, for 18490.
